TO ALL WIIOM IT MAY CONCERN:

Bc it known that I, WILLAM HAMER, of Little Lever, near Bolton, in thecounty of Lancaster, England, have invented a new and improved ApparatusEmployed in the Preparation of Cotton and other Fibrous Materials; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this spceication, in which- Figure 1 is a verticalsection of a can, having in it a. plate and spira-l spring, forassisting the removal of' the sliver.

Figure 2,"a plan of the bottom of the can.

Figure 3, aplan of the movable plate only.

Similar letters of reference indicate corresponding parts.

This invention relates to the removalof the sliver from the can orcoiler, and consists in placing underneath the material a. spring ofmetal, so that, as the sliver is4 removed from the top of the can orcoller, its lower portion is raised upwards by the spring, and therebyprevents breakage.

In fig. 1 the can is'shown at a, the plate at b, and the spiral springatc. In fig. 2, d represents a hole in the bottom of the can, foradmitting air during the removal of the sliver; and in lig. 3 the plateis shown detached. The spring of metal is formed of round, square, orother shaped wires, and is made of any number of coils, according to thesize of the can and weight of material, and is applied to cans orcoilers of all descriptions and purposes.

When the sliver is drawn up in the usual manner, it frequently becomesuneven, stretched, torn, or broken; but the application of my improvedspring and plate causes the sliver to be gradually raised up from thebottom to near the top of the delivery, and, by taking oil' the strain,enables the sliver to be made as line as possible, and prevents defectsor breakage when' leaving the can.

By the employment of my improved spring arid plate usual, and therebyhold more material they also require less tending and shifting, and haveless wear and tear. Another advantage is thatthe pressure upon thesliver is commenced soon after` it has begun to enter the can,andthereby enables it to be laid even and regular Having new describedthe nature and particulars of my said invention, and the mannerin whichthe same is to be performed, I claim as my invention, and desire tp.secure by Letters Patent- The spiral spring c, supporting the movablemetal plate b in the can a, having the perforated bottom, allconstructed and operating as described, forxhe purpose specified.

The above speciication of my invention signed by me this flfth day ofMarch, 1867.
